Use of config files to create specific configs for all camera models

Previously, a difficulty was that different camera models had different accessible attributes and attribute names.
Instead of making a plugin that handles all those cases, the plugin now relies on model-specific config files, in which the user can easily choose the attributes they want to expose.

For a given camera model, if no config file is present, the plugin will offer to create a new config file (eg in .pymodaq/config_acA645-100gm.json) with basic attributes (exposure and gain), whose names will be automatically adapted to the available attributes. The style of the .json configuration files follows the usual pymodaq config files.
